DESCRIPTION (provided by applicant): The Southeastern United States has the fastest growing Latino population in the country and at the same time carries a disproportionate HIV/AIDS disease burden. We propose a 2-year exploratory study (R21) to understand and characterize social and sexual networking patterns and socio-cultural and psychological correlates of sexual risk within a population about which little is currently known: newly-arrived, less-acculturated Latino gay men and Latino men who have sex with men (MSM) living in the rural Southeast. The AIDS case rate for Latino men is over 3 times that for non-Latino white men. The most common means of HIV transmission among Latinos is through same-sex sexual behavior. Among Latino gay men and Latino MSM in North Carolina, condom use rates are considerably lower than rates reported in other parts of the US. In a sample of MSM recruited in 3 bars in central NC, 69% of Spanish-preferring Latino MSM who reported having anal intercourse within the past 3 months reported inconsistent condom use with non-steady male partners. We also found that 32% reported having sex with both men and women within the past 3 months, and none of the men reported having ever been tested for HIV. Little is known about these men's social and sexual networking patterns and risk behaviors. This study will generate scientific knowledge and understanding needed to characterize risk and help identify potentially effective intervention approaches and strategies to reduce HIV exposure and transmission within this population. We will use 3 modes of data collection: (a) 30 rural Latino gay men and Latino MSM will complete iterative in-depth interviews (each respondent will be interviewed 3 times) to gain "insider" perspectives on HIV risk and prevention; (b) 16 local Latino-service and health providers will complete one-time in-depth interviews to gain "outsider" perspectives on HIV risk and prevention; and (c) 211 rural Latino gay men and Latino MSM will complete an interviewer- administered assessment to be developed based on formative interview data, through respondent-driven sampling (RDS). RDS is an innovative statistical approach to sampling to provide unbiased population estimates when a predetermined sampling frame is unknown. The proposed study will advance the field of HIV prevention research by generating in-depth knowledge necessary to develop culturally-appropriate models to better explain condom use within vulnerable communities: recently arrived, less-acculturated Latino gay men and Latino MSM who live in the rural Southeast. Study findings also will help shape new multilevel intervention approaches and strategies to reduce the disproportionate HIV/AIDS disease burden of Latino men.

描述（由申请人提供）：美国东南部地区是该国拉丁裔人口增长最快的地区，同时也承担着不成比例的艾滋病毒/艾滋病疾病负担。我们提出一项为期 2 年的探索性研究 (R21)，以了解和描述目前知之甚少的人群中的社会和性网络模式以及性风险的社会文化和心理相关性：新来的、文化程度较低的拉丁裔男同性恋者以及生活在东南部农村的男男性行为者 (MSM) 的拉丁裔男性。拉丁裔男性的艾滋病发病率是非拉丁裔白人男性的 3 倍以上。拉丁美洲人中最常见的艾滋病毒传播途径是同性性行为。在北卡罗来纳州的拉丁裔男同性恋者和拉丁裔男同性恋者中，安全套的使用率远低于美国其他地区的报告率。在北卡罗来纳州中部 3 家酒吧招募的 MSM 样本中，在过去 3 个月内进行过肛交的喜欢西班牙语的拉丁裔 MSM 中，69% 的人表示与不稳定的男性伴侣不一致地使用安全套。我们还发现，32% 的人报告在过去 3 个月内与男性和女性发生过性行为，而且这些男性中没有一人报告曾接受过 HIV 检测。人们对这些男性的社交和性网络模式以及危险行为知之甚少。这项研究将产生描述风险所需的科学知识和理解，并帮助确定潜在有效的干预方法和策略，以减少该人群中艾滋病毒的暴露和传播。我们将采用 3 种数据收集模式： (a) 30 名农村拉丁裔男同性恋者和拉丁裔 MSM 将完成迭代式深度访谈（每位受访者将接受 3 次访谈），以获得有关艾滋病毒风险和预防的“内部”观点； (b) 16 名当地拉丁裔服务和保健提供者将完成一次性深度访谈，以获得关于艾滋病毒风险和预防的“局外人”观点； (c) 211 名农村拉丁裔男同性恋者和拉丁裔 MSM 将通过受访者驱动抽样 (RDS)，根据形成性访谈数据完成访谈者管理的评估。 RDS 是一种创新的统计抽样方法，可在预定抽样框未知时提供无偏总体估计。拟议的研究将通过生成必要的深入知识来推进艾滋病毒预防研究领域，以开发适合文化的模型，以更好地解释弱势社区中安全套的使用情况：新近抵达、文化程度较低的拉丁裔男同性恋者和居住在农村的拉丁裔男同性恋者东南。研究结果还将有助于制定新的多层次干预方法和策略，以减少拉丁裔男性不成比例的艾滋病毒/艾滋病疾病负担。
